1 Claim.

My present invention relates to an improved door stop of the typeadapted to'be secured to the lower portion of the door and pivotallymovable manually to engaging position with regard to the floor so as toretain the door in set position.

The stop of my invention consists generally in a body having a fiat sidefor engagement with the floor and a curved side, the two said sidesbeing eccentric so that the curved side clears the floor while the flatside when swung down engages the floor. Spring means associated witheccentric pinson the shafts of the body releasably retain the body inadjusted position.

In the accompanying drawings I have illustrated one complete example ofthe physical em-- bodiment of my invention according to the best mode Ihave thus far devised, but it will be understood that various changesand alterations may be made in the exemplified structure within thescope of the appended claim.

In the drawings:

Figure l is an end elevational view of the door stop of my invention innon-engaging position.

Figure 2 is a similar view showing the stop partially pivoted and readyfor engagement.

' Figure 3 is a similar view showing the fiat side of the stop engagingthe floor.

Figure 4 is a front elevational view of the stop.

Figure 5 is a top plan view thereof.

Referring now to the drawings wherein I have illustrated the presentpreferred embodiment of my invention I have shown the door stop of myinvention as used with the door 2 and comprising the bracket or baseplate 4 secured to the lower portion of the door as by screws 6. Thebracket plate has outwardly extended springs 8 formed at their ends intocurved journals ID for the ends of the stud shaft 12 of the stop body M.This body has a pair of flat parallel walls, a flat side I6 and anarcuate side I8, the stud shaft being located eccentric of the body withthe center thereof spaced a greater distance from the flat side thanfrom the arcuate side, whereby the arcuate side clears the floor whilethe fiat side will engage the floor with the stop inverted. The corners20 at the ends of the fiat side are rounded and the sides between thefiat and curved sides are inclined.

On the shafts I2 I provide eccentric pin extensions 22 which engagespring arms 24 also extending outwardly of the bracket plate 4 and theeccentric pins are positioned to tension the elements and resilientlyhold the stop body when the fiat side is down. These spring arms merelybear upon the pins when the body is up.

As shown in the various views the fiat side of the body is normally upand is retained in that position by the spring arms acting upon theeccentric pins.

However to secure the door the body is swung manually until the corner20 engages the floor whereupon the door is moved slightly to completethe pivotal movement and bring the fiat side into parallel position withthe floor and in engagement therewith under tension of the spring arms 8and the pins.

Retrograde movement of the door will pivot the stop in reverse positionand put the curved side down to clear the floor.

The door stop of my invention is simple to manufacture and use and maybe installed with a minimum of tools and effort and will securely securethe door in selected position.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

A door stop comprising a base plate having spaced pairs of adjustingposition outwardly extended spring arms, the inner of said spring armsof each pair having cylindrical sockets in the ends thereof, a bodyhaving a flat base with an arcuate upper side, and a shaft extendedthrough said body and positioned on a center a greater distance from theflat side of the body than from the arcuate side, the ends of said shaftbeing journaled in the cylindrical sockets at the ends of said springarms, the said ends of the shaft having pins eccentrically positionedthereon and extended therefrom, and said pins positioned to engage theouter of said spring arms of the pairs extended outwardly from the baseplate whereby the said body is resiliently retained in a position withthe flat side thereof extended upwardly.
